UPSC Editorials Quiz : 1 January 2026

Introducing QUED – Questions from Editorials (UPSC Editorials Quiz) , an innovative initiative from InsightsIAS. Considering the significant number of questions in previous UPSC Prelims from editorials, practicing MCQs from this perspective can provide an extra edge. While we cover important editorials separately in our Editorial Section and SECURE Initiative, adding QUED (UPSC Editorials Quiz) to your daily MCQ practice alongside Static Quiz, Current Affairs Quiz, and InstaDART can be crucial for better performance. We recommend utilizing this initiative to enhance your preparation, with 5 MCQs posted daily at 11 am from Monday to Saturday on our website under the QUIZ menu.

• Question 1 of 5 1. Question Which of the following are characteristic symptoms of Attention Deficit Hyperactivity Disorder (ADHD)? Difficulty maintaining focus on tasks or activities. Excessive energy and physical restlessness. Chronic memory loss. Acting without considering consequences. Select the correct answer: a) 2, 3, and 4 only b) 1, 2, and 3 only c) 1, 2, and 4 only d) 1, 2, 3 and 4 Correct Solution: C Difficulty focusing (1), restlessness (2), and impulsivity (4) are hallmark symptoms of ADHD. Chronic memory loss (3) is not typically associated with ADHD; rather, ADHD involves forgetfulness related to inattention. About Attention Deficit Hyperactivity Disorder (ADHD): What is ADHD? A neurodevelopmental disorder affecting focus, impulsivity, and hyperactivity. Commonly diagnosed in childhood but often persists into adulthood. Impacts 3-4% of adults worldwide. Causes: Genetics: Family history significantly increases the risk. Brain Structure: Alterations in the brain regions responsible for attention and behaviour regulation. Prenatal Factors: Exposure to tobacco, alcohol, or drugs during pregnancy. Environmental Factors: Lead exposure and low birth weight. Symptoms: Inattention: Difficulty focusing, forgetfulness, frequent mistakes, or being easily distracted. Hyperactivity: Restlessness, excessive movement, or inability to stay still in quiet situations. Impulsivity: Interrupting conversations, acting without thinking, and engaging in risky behaviours. Treatment: Medication: Stimulants (e.g., methylphenidate, amphetamines) and non-stimulants (e.g., atomoxetine). Behavioural Therapy: Focuses on developing coping mechanisms and organizational skills. Lifestyle Changes: Balanced diet and regular exercise. Adequate sleep to improve focus and mood. Counselling: Helps manage impulsivity, risky behaviours, and emotional difficulties.

• Question 2 of 5 2. Question Consider the following statements about Black Panthers: They are found across Asia, Africa, and the Americas. The presence of melanism makes black panthers a separate subspecies. Black leopards are more common in dense tropical rainforests due to better camouflage. How many of the above statements are incorrect? a) Only one b) Only two c) All three d) None Correct Solution: A Statements 1 and 3 are correct. Black panthers (melanistic leopards or jaguars) are found across Asia, Africa, and the Americas, and their dark color provides better camouflage in dense forests. Statement 2 is incorrect because black panthers are not a separate subspecies but a melanistic variant. What is a Black Panther? The black panther, a colloquial term for melanistic (dark-colored) large felines in the genus Panthera, is known for its striking black fur and mysterious allure. Scientific Names: Black Leopard: Panthera pardus. Black Jaguar: Panthera onca. Habitat: Found across three continents: Asia, Africa, and the Americas. Commonly inhabit dense tropical rainforests, grasslands, and mountainous regions. Global Range: Southwest China, Southern India, Nepal, Malaysia, Indonesia, Burma. Indian Range: Found in Kabini Forest (Karnataka), Nagarhole National Park, Periyar Wildlife Sanctuary, Silent Valley, and Sundarbans. Characteristics: Physical Features: Glossy black or dark brown fur with faint spotted patterns visible in sunlight. Eyes: Striking emerald green, giving a fierce and elegant look even in darkness. Behavioural Traits: Solitary and territorial hunters. Known for exceptional intelligence, sharp eyesight, and strong sense of smell. Males are polygamous in nature. Why Black Color? Melanism results from specific genetic alleles: Recessive alleles in leopards. Dominant alleles in jaguars. The high concentration of melanin creates their dark fur, aiding camouflage in dense forests. Conservation Status: IUCN Red List: Vulnerable. CITES: Appendix I (strictly regulated trade). Indian Wildlife (Protection) Act, 1972: Schedule I (maximum protection). Threats: Habitat loss, poaching, and declining prey populations. Incorrect Solution: A Statements 1 and 3 are correct.

• Question 4 of 5 4. Question Which of the following is the most common risk factor for developing Chronic Pulmonary Aspergillosis (CPA)? a) High-altitude living with low oxygen levels b) Exposure to second-hand smoke c) Long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) d) Recent recovery from tuberculosis or other lung infections Correct Solution: D CPA commonly occurs in individuals with pre-existing lung damage caused by infections such as tuberculosis (TB), sarcoidosis, or chronic obstructive pulmonary disease (COPD). The damaged lung tissue creates a favorable environment for Aspergillus fungus to colonize. Secondhand smoke, NSAIDs, or high-altitude living are not significant risk factors for CPA. About Chronic Pulmonary Aspergillosis (CPA): What is CPA? Chronic Pulmonary Aspergillosis is a severe lung infection caused by Aspergillus fumigatus, a fungus that predominantly strikes individuals with immunodeficiency or pre-existing lung conditions, particularly those with a history of TB. Vector: The infection is caused by inhalation of fungal spores (*Aspergillus fumigatus*), which thrive in decayed organic matter and humid environments. Symptoms: Chronic cough Haemoptysis (coughing up blood) Fatigue and weight loss Persistent respiratory distress Impact: High morbidity and mortality rates if left undiagnosed or untreated. CPA prevalence in Assam (60 per 1,00,000) exceeds the global average (42 per 1,00,000), and is worse than several African nations, including Nigeria and Congo. Treatment: Early diagnosis through serological testing for Aspergillus antibodies and radiological imaging. Antifungal therapy (e.g., itraconazole or voriconazole). Public health campaigns to educate healthcare workers and communities on respiratory health, nutrition, and hygiene.

• Question 5 of 5 5. Question Consider the following statements regarding the comparison between seas and oceans: Oceans are deeper than seas, with the Challenger Deep being the deepest point in the ocean system. Seas generally have higher salinity levels compared to oceans due to evaporation and minimal water exchange. Both seas and oceans equally influence global climate regulation by distributing solar energy. How many of the above statements are correct? (a) Only one (b) Only two (c) All three (d) None Correct Solution: B Oceans are significantly deeper than seas, with Challenger Deep (~36,070 ft) being the deepest point in the ocean system. Seas often have higher salinity due to their limited water exchange and higher evaporation rates. However, oceans play a more dominant role in global climate regulation compared to seas, making statement 3 incorrect. About difference between Sea and Ocean: Aspect Sea Ocean Geographical Location Smaller bodies of saltwater, mostly enclosed by land and connected to oceans via straits. Large, continuous bodies of saltwater covering 71% of Earth’s surface, part of the global system. Size Smaller in area and volume, typically located along coastal boundaries. Much larger, spanning vast areas and depths. Depth Shallower, with depths ranging from hundreds to a few thousand feet (e.g., Mediterranean Sea: ~4,900 ft). Deeper, with an average depth of ~12,080 ft and the deepest point, Challenger Deep (~36,070 ft). Salinity Higher salinity due to evaporation, minimal water exchange, and river inflow (e.g., Dead Sea). Stable salinity (average ~35 ppt) due to continuous water movement. Climate Influence Impacts local climates, especially coastal regions, by moderating temperatures. Plays a major role in global climate regulation by absorbing and distributing solar energy.
